Q&A: Supernova Remnants and Neutron Stars
What is the size of, X-ray energy of and exposure time of the
image of the Crab Nebula? 2) What is the presumed orientation of
the X-ray image versus that of the pulsar? i.e.: The jets in the
X-ray image, are they coincident with the rotation axis of the
The largest angular size of the image from the jet on the lower
left to the upper right, is about 2'20"; the inner ring is about
30" in diameter.
The energy band is roughly 0.5 to 10 keV; The exposure time was
12,000 sec. Presumably the X-ray jet is oriented along the
magnetic pole, or maybe the rotation axis of the pulsar.
